Seattle nearly made Montero’s 14th-minute tally last, holding the visitors for 30 minutes after losing teenager Miguel Montano to a red card in the 56th minute. But they couldn’t deny Ferreira, who has notched either a goal or an assist in the Hoops’ past five matches.

Looking to break a three-match losing streak, Sounders coach Sigi Schmid went with youth against FCD, dropping veterans Pat Noonan, Pete Vagenas, Tyrone Marshall and the injured Freddie Ljungberg from the starting unit. Dallas came out with essentially the same lineup that has led them to a three-match winning streak, led by the imposing Atiba Harris up front.

FCD’s Brek Shea nearly opened the scoring with an uncontested header in the sixth minute. Minutes earlier, Harris forced a save from Kasey Keller after a failed clearance from Patrick Ianni along the end line as Dallas looked threatening early.

After the shaky start, Seattle started to find their footing and almost scored through an FCD miscue by George John in the ninth minute. The defender will thank goalkeeper Kevin Hartman for rescuing him after his ill-advised back pass went directly Seattle’s Montero, whose shot was just saved.

But Montero’s luck improved five minutes later. Finding space in the Dallas back line, the Colombian headed home James Riley’s cross from the touchline for his team-leading sixth goal of the season.

Looking to equalize, the visitors’ task became easier after a rush of blood by Seattle’s youngest player. Involved in a skirmish with Shea in front of the FC Dallas bench, 19-year-old Montano lashed out at the FCD winger and received a straight red card from referee Kevin Stott.

With the man advantage, Dallas began to control possession as they searched for the equalizer. Keller had to come off his line twice to thwart FCD attempts as the Rave Green shrunk into a defensive shell.

As the second ticked by, it looked like Seattle would escape with all three points. But with the man advantage and momentum on their side, Dallas kept pressing. Three minutes from time, Ferreira worked a beautiful give-and-go with defender Heath Pearce, lashing a shot inside the far post for the final margin that extended FCD's unbeaten streak to five consecutive matches.

FC Dallas host Real Salt Lake next Saturday in a matchup of two of the league’s hottest teams. Seattle, meanwhile, face a short week, flying cross-country to take on D.C. United in a nationally televised encounter on Thursday.
